Progression-free survival as a potential surrogate for overall survival in metastatic breast cancer
BACKGROUND Progression-free survival (PFS) and time to progression (TTP) are frequently used to establish the clinical efficacy of anti-cancer drugs. However, the surrogacy of PFS/TTP for overall survival (OS) remains a matter of uncertainty in metastatic breast cancer (mBC). This study assessed the relationship between PFS/TTP and OS in mBC using a trial-based approach. METHODS WE CONDUCTED ...
متن کاملEstimating changes in overall survival using progression-free survival in metastatic breast and colorectal cancer.
OBJECTIVES In clinical trials of new cancer drugs, reliable data for progression-free survival will often become available far sooner than reliable data for overall survival. The aim of this study was to determine how many months it would be expected that any given new drug for metastatic breast or colorectal cancer will add to overall survival times given that the number of months the drug add...
متن کاملProgression-free survival as a surrogate for overall survival in advanced/recurrent gastric cancer trials: a meta-analysis.
The traditional endpoint for assessing efficacy of chemotherapies for advanced/recurrent gastric cancer is overall survival (OS), but OS requires prolonged follow-up. We investigated whether progression-free survival (PFS) is a valid surrogate for OS. Using individual patient data from the GASTRIC meta-analysis, surrogacy of PFS was assessed through the correlation between the endpoints and thr...
متن کاملEvaluation of progression-free survival as a surrogate endpoint for survival in chemotherapy and targeted agent metastatic colorectal cancer trials.
Pooled analyses of chemotherapy trials in metastatic colorectal cancer (mCRC) have suggested that progression-free survival (PFS) is a surrogate endpoint for overall survival (OS). However, this has not been evaluated under current standard-of-care regimens of chemotherapy in combination with targeted therapies. We conducted an analysis of published mCRC trials of chemotherapy and targeted ther...
متن کاملSurrogacy of progression free survival for overall survival in metastatic breast cancer studies: Meta-analyses of published studies.
PURPOSE PFS is often used as a surrogate endpoint for OS in metastatic breast cancer studies. We have evaluated the association of treatment effect on PFS with significant HROS (and how this association is affected by other factors) in published prospective metastatic breast cancer studies. METHODS A systematic literature search in PubMed identified prospective metastatic breast cancer studie...
